EYEWEAR LENS COLOR REFERENCE GUIDE
For Industrial application purposes, this
Lens Color Reference Guide
will help you understand the
functionality of “task-specific” lenses and how to determine what type of lens is best for your
application and environment.
It is important to understand
why there are more lens color options
,
often necessary, than a Clear, Gray or Mirror lens. The basic rule of thumb for choosing a lens is to
consider color opposites.
Blue
is opposite of Yellow and
Red
is opposite of
Green
. Therefore,
Red
lenses
will absorb
Green
light and Yellow Lenses will absorb
Blue/
Ultraviolet
light, and vice versa
.
Try on the
different AOSafety lenses and learn for yourself the differences, functions and benefits of
the different lens colors.
Yellow/Contrast Amber Lens –
absorbs Blue and Ultraviolet light
Use a Contrast Amber lens when sharpness, acuity and contrast are needed and to block high
intensity blue lighting such as UV and in Curing Operations. #1 Use is UV absorption.
•
Filters out hazy light that is hard on the eyes (everything seems brighter)
•
Good for working outside at Dawn and Dusk
•
Good for hazy, overcast or foggy days (because of the blue/gray light, similar to the function of a
fog light)
•
Should not be used where protection from infrared radiation is required or for night time driving
Red
/
Vermilion
Lens –
absorbs some Green light
Sharpens visual acuity and provides a contrast similar to the Contrast Amber lens. Some people
prefer the Vermilion to the Amber lens when choosing a lens to sharpen visual acuity.
•
Good for inspections because you can see defects better – circuit boards, miniature components,
assembly items, etc.
•
Filters out light that is hard on the eyes
•
Not as good for outside at Dawn or Dusk as a Contrast Amber lens
Green/I.R. Shade Lens –
blocks Red/Infrared (I.R.) light
Use any place where there is heat.
•
Good for metal making, furnace work, trash incineration and open flames
•
Protects against glare, ultraviolet and infrared radiations
•
Available in Shade 3.0 or 5.0
Gray/Silver Mirror/Blue Mirror Lenses
–
reduce glare and bright light
Use to reduce glare and/or to decrease visible brightness
•
Good for outdoor applications where a task specific lens is not required
•
Can still recognize traffic and warning signals
•
Provides good color recognition (utility workers and linespeople)
•
Mirror reflects light, reducing the amount of light that passes through the lens
